Description

Technical Field

[0001] This utility model relates to the field of automotive floor grinding technology, and in particular to an automotive floor grinding device. Background Technology

[0002] In the automotive manufacturing and repair industry, edge grinding of the car floor is a crucial process. As an important component of the car chassis, the flatness, smoothness, and fit of the car floor edges with surrounding parts not only affect the overall appearance quality of the car, but also directly relate to various aspects of the car's performance, such as safety, stability, and noise control during driving.

[0003] However, in actual production and repair scenarios, the shape, size, and installation location of automotive floor panels often vary considerably. Different car models have different floor panel designs, with varying curves and angles at the edges. Moreover, during automotive repair, the floor panel may have experienced collisions, deformations, etc., damaging its original edge shape and requiring edge grinding to restore it to its normal state.

[0004] A fixed-angle grinding method makes it difficult to guarantee consistent grinding quality. Traditional automotive floor panel edge grinding devices are mostly simple in structure and single in function, with the grinding angle usually fixed. For some edges with special angles, due to the inability to accurately match the grinding angle, it is easy to over-grind or under-grind, resulting in uneven floor panel edges, burrs, and other problems, which in turn affect the assembly accuracy and performance of the automotive floor panel. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automotive floor grinding device, which aims to improve the problem that the grinding angle of traditional automotive floor grinding devices is usually fixed, resulting in uneven edges and burrs on some special angle edges.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A grinding device for automotive floor panels includes a fixed frame and a mounting frame. One end of a slide rod is fixedly connected to the outer wall of the mounting frame, and a fixed plate is fixedly connected to the other end of the slide rod.

The grinding block is rotatably connected to the fixed plate. A support assembly is provided on the outer wall of the fixed frame.

[0008] Preferably, the support assembly includes a telescopic rod, the outer wall of which is fixedly connected to the outer wall of the fixed frame, and a sleeve is fixedly connected to the outer wall of the telescopic rod.

[0009] Preferably, a second motor is installed on the upper surface of the outer wall of the fixed frame, and a second lead screw is fixedly provided at the output end of the second motor. The outer wall of the second lead screw is threadedly connected to a second sliding frame and a third sliding frame.

[0010] Preferably, the sliding frame 2 and the sliding frame 3 are internally slidably connected by a sliding rod 2, and both ends of the sliding rod 2 are fixedly connected to the outer wall of the fixed frame.

[0011] Preferably, both the sliding frame two and the sliding frame three are rotatably connected to a bevel gear one.

[0012] Preferably, a motor is installed on the inner top wall of the fixed frame, and a spline shaft is fixedly provided at the output end of the motor. The bevel gears on the upper and lower sides are slidably connected to the outer wall of the spline shaft.

[0013] Preferably, the tooth ends of the first bevel gear are meshed with the second bevel gear, and the upper and lower bevel gears are respectively rotatably connected inside the sliding frame second and the sliding frame third.

[0014] Preferably, the outer wall of the second bevel gear is fixedly connected to a rotating shaft, the rotating shaft is fixedly connected to the mounting bracket, and the outer wall of the rotating shaft is rotatably connected to the inner wall of the sleeve.

[0015] This utility model has the following beneficial effects:

[0017] 2. In this utility model, motor 2 drives lead screw 2 to rotate, causing sliding bracket 2 and sliding bracket 3 to slide in opposite directions on sliding rod 2, which drives the upper and lower bevel gears 1 to slide to change the distance. At the same time, motor 3 drives spline shaft to rotate. Through the meshing of bevel gear 1 and bevel gear 2, the rotating shaft drives the mounting bracket to rotate, realizing simultaneous grinding on the upper and lower sides.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a car floor grinding device, including a fixed frame 1 and a mounting frame 2. One end of a slide rod 3 is fixedly connected to the outer wall of the mounting frame 2, and the other end of the slide rod 3 is fixedly connected to a fixed plate 4. A motor 5 is mounted on the outer wall of the mounting frame 2. A lead screw 6 is fixedly provided at the output end of the motor 5. A sliding frame 7 is threadedly connected to the outer wall of the lead screw 6. The sliding frame 7 is slidably connected to the outer wall of the slide rod 3. A connecting rod 8 is rotatably connected to the outer wall of the sliding frame 7. A grinding block 9 is rotatably connected to the outer wall of the connecting rod 8. The grinding block 9 is rotatably connected to the fixed plate 4. A support assembly is provided on the outer wall of the fixed frame 1.

[0026] Specifically, mounting bracket 2 fixes slide rod 3 and fixing plate 4. Starting the fixing plate 4 drives the lead screw 6 at the output end to rotate. The rotation of lead screw 6 drives slide frame 7 to slide. Slide rod 3 supports the sliding of slide frame 7. The sliding of slide frame 7 drives connecting rod 8 to rotate. The rotation of connecting rod 8 pushes the grinding block 9 to rotate. When the grinding block 9 rotates, its angle can be adjusted to facilitate grinding at different angles.

[0027] Reference Figure 1The support assembly includes a telescopic rod 10, the outer wall of which is fixedly connected to the outer wall of the fixed frame 1, and a sleeve 11 is fixedly connected to the outer wall of the telescopic rod 10.

[0028] Specifically, the sleeve 11 is used to support the rotation of the grinding head, while the telescopic rod 10 extends and retracts.

[0029] Reference Figure 1 and Figure 4 A motor 12 is installed on the upper surface of the outer wall of the fixed frame 1. A lead screw 13 is fixedly installed at the output end of the motor 12. A sliding frame 15 and a sliding frame 16 are threadedly connected to the outer wall of the lead screw 13. A sliding rod 14 is slidably connected inside the sliding frame 15 and the sliding frame 16. Both ends of the sliding rod 14 are fixedly connected to the outer wall of the fixed frame 1.

[0030] Specifically, the starter motor 12 drives the lead screw 13 at the output end to rotate, the lead screw 13 pushes the sliding frame 15 and the sliding frame 16 to slide, the sliding frame 15 and the sliding frame 16 slide in opposite directions, and the slide rod 14 supports the sliding frame 15 and the sliding frame 16 to slide in opposite directions.

[0031] Reference Figure 1 and Figure 4 Both sliding frame 2 15 and sliding frame 3 16 are rotatably connected to bevel gear 17; motor 3 18 is installed on the inner top wall of fixed frame 1, and spline shaft 19 is fixedly installed at the output end of motor 3 18. Bevel gear 17 on both the upper and lower sides is slidably connected to the outer wall of spline shaft 19; bevel gear 20 is meshed with the tooth end of bevel gear 17, and bevel gear 20 on both the upper and lower sides is rotatably connected to the interior of sliding frame 2 15 and sliding frame 3 16 respectively; rotating shaft 21 is fixedly connected to the outer wall of bevel gear 20, rotating shaft 21 is fixedly connected to mounting frame 2, and the outer wall of rotating shaft 21 is rotatably connected to the inner wall of sleeve 11.

[0032] Specifically, when sliding bracket 2 15 and sliding bracket 3 16 slide in opposite directions, they drive the upper and lower bevel gears 17 to slide, which can change the distance between the upper and lower bevel gears 17. At the same time, sliding bracket 2 15 and sliding bracket 3 16 drive bevel gear 20 to slide, and start motor 3 18 drives the spline shaft 19 at the output end to rotate. The spline shaft 19 drives bevel gear 20 to rotate through bevel gear 17. Bevel gear 20 drives the mounting bracket 2 to rotate through the rotating shaft 21 for grinding. Grinding can be performed on both the upper and lower sides at the same time, and the distance between the upper and lower sides is adjustable to adapt to base plates of different thicknesses.

[0033] Working principle: When using this car floor grinding device, comprehensive preparation work must be carried out first to ensure that the connection is firm and that all parts of the device are operating normally. When it is necessary to grind the car floor, according to the actual grinding angle required, start the motor 5 installed on the outer wall of the mounting bracket 2. The output end of the motor 5 starts to rotate and drives the lead screw 6 fixed to it to rotate. Under the action of the lead screw 6 rotating, the sliding bracket 7 threadedly connected to it slides along the slide rod 3. During the sliding process, the sliding bracket 7 drives the connecting rod 8 to rotate, and the connecting rod 8 pushes the grinding block 9 to rotate, thereby adjusting the grinding block 9 to a suitable grinding angle and making full preparations for the subsequent grinding operation.

[0034] After adjusting the angle of grinding block 9, the grinding distance on the upper and lower sides needs to be adjusted according to the thickness of the car floor. Start the motor 12 mounted on the upper surface of the outer wall of the mounting bracket 1. The output end of motor 12 begins to rotate, driving the lead screw 13 fixed to it to rotate. The lead screw 13 pushes the sliding brackets 15 and 16 to slide in opposite directions under the support of the sliding rod 14. This sliding method changes the distance between the upper and lower bevel gears 17, simultaneously driving the bevel gear 20 to slide. Then, start the motor 18 mounted on the inner top wall of the mounting bracket 1. The output end of motor 18 begins to rotate, driving the lead screw 13 fixed to it to rotate. Spline shaft 19 rotates, and spline shaft 19 drives bevel gear 20 to rotate through bevel gear 17. Bevel gear 20 then drives mounting bracket 2 to rotate through rotating shaft 21 fixedly connected to it. The rotation of mounting bracket 2 causes grinding block 9 to rotate accordingly. During the grinding process, sleeve 11 in support assembly provides support for the rotation of grinding head. Telescopic rod 10 can extend and retract accordingly to cooperate with the operation of the device and ensure the smooth progress of the entire edge grinding operation. The edge grinding operation of the car floor begins. Due to the special design of the device, it can grind the upper and lower sides at the same time, and the distance between the upper and lower sides is adjustable, so it can adapt to the edge grinding needs of car floor panels of different thicknesses.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
